BACKGROUND

Random access requests are requests made by a wireless device for accessto a network via one or more base stations.

Often, such background process-related connection requests maycompete (for network resources) with foreground process-relatedconnection requests, which can degrade a user experience in connectionwith foreground process-related activity.

DETAILED DESCRIPTION

FIG. 1 illustrates a system 100 for restricting a random accessprocedure that originates from an application running in the backgroundon a wireless communication device 104A, in accordance with oneembodiment. As shown, the wireless communication device 104A is incommunication with a base station 106 which, together, form atelecommunication network 108. Such network 108 may further include atleast one other wireless communication device 104B, as shown.

Non-limiting examples of the foregoing base station 106 may include aNode B, multi-standard radio (MSR) radio node such as an MSR BS, eNodeB, network controller, radio network controller (RNC), base stationcontroller (BSC), relay, donor node controlling relay, base transceiverstation (BTS), access point (AP), transmission point, transmissionnodes, remote radio unit (RRU), remote radio head (RRH), node in adistributed antenna system (DAS), a cell node, and/or any otherapparatus that is configured for communicating with the wirelesscommunication device 104A over the telecommunication network 108.Further, the wireless communication device 104A (or simply “wirelessdevice”) may, in various embodiments, include a phone, a tablet, alaptop, a vehicle, any desired type of user equipment (UE), and/or anyother type of device capable of communicating on the aforementionedtelecommunication network 108 or any other type of network, for thatmatter.

Still yet, in various embodiments, the telecommunication network 108 mayinclude any network including, but not limited to a 3G network, a 4Gnetwork, a 5G network, a long term evolution (LTE) or LTE-Advancednetwork, or any advanced permutation thereof. It should be noted,however, that use of other radio access technology (RAT) networks (e.g.BLUETOOTH, WiFi, etc.) are contemplated, as well.

In use, the wireless devices 104A, 104B (and others not shown) may eachattempt to connect the base station 106 by sending a random accessrequest thereto. The purpose of such random access request is for thewireless devices 104A, 104B to gain access to resources of thetelecommunication network 108 via the base station 106, so thatcommunication (e.g. transmissions, reception) may ensue with otherdevices (e.g. other wireless devices, data servers, etc.). In variousembodiments, such random access request may take any format and/orfollow any protocol, an example of which will be set forth during thedescription of an embodiment illustrated in FIG. 2B.

It should be noted that the aforementioned random access requests may beinitiated by the wireless devices 104A, 104B in different ways. Forexample, the random access requests may be caused or otherwise promptedby a connection request that is initiated in response to a user of aparticular wireless device manually initiating a call by entering aphone number via a phone application. As yet another example, theforegoing connection request may be initiated in response to the user ofthe particular wireless device manually executing or otherwisecontrolling an application. For instance, such user may open a networkbrowser and, by manipulating controls of the network browser, thewireless device may initiate a request for or transmission of datawhich, in turn, requires the initiation of the aforementioned connectionrequest and resulting random access request. Of course, use of otherapplications are contemplated including, but not limited to officeproductivity applications, gaming applications, social networkapplications, etc. In each of the foregoing examples, the application(e.g. the phone application, network browser, etc.) runs as foregroundprocess.

As yet another example of how a connection request may be initiated, anapplication may initiate such connection request while running as abackground process. For instance, an electronical mail (e-mail)application may periodically require a download of any incoming messagesfrom a corresponding data server. Further, this may occur while theparticular wireless device is being used by the user to access and/orinteract with another application (in the foreground), or while theparticular wireless device is not being actively used by the user at all(e.g. while in standby mode, when the screen or other user input/outputis deactivated, etc.).

Thus, in the context of the present description, such background processmay refer to any process that is capable of being carried out by awireless device without real-time user intervention. In contrast, theaforementioned foreground process may refer to any process that that iscarried out by a wireless device in immediate response to real-time userinput.

Given the foregoing different ways that connection requests andresulting random access requests may be initiated by the wirelessdevices 104A, 104B, situations may arise where the telecommunicationnetwork 108 is incapable of serving all random access requests. This isparticularly the case where a number of the wireless devices 104A, 104Bis large or otherwise exceeds a capability of the base station 106.While such situation may impact all of the aforementioned random accessrequests (and whether they can be serviced), connection requestsresulting from foreground processes (e.g. active user calls, real-timeuser data requests, etc.) may be most perceptible to users, since theuser is actively interacting and requesting service from such processes.

In such situations, the system 100 is capable of handling backgroundprocess-related connection requests differently as compared toforeground process-related connection requests. Specifically, aconnection request-prompted random access preamble transmission may berestricted in any desired manner including, but not limited to delayingsuch random access preamble transmission, reducing a frequency of suchpreamble transmission, reducing a number of such preamble transmissions,delaying the aforementioned background process-related connectionrequest, etc. By this design, an overall number of random accesspreamble transmissions may be reduced during a given time. Moreinformation regarding such techniques will be set forth during thedescription of subsequent embodiments. In any case, the base station 106is more likely to sufficiently service the foreground process-relatedconnection requests, in order to reduce a likelihood of (or eveneliminate) any perceptible reduction in service.

FIG. 2A illustrates a method 200 for restricting a random accessprocedure that originates from an application running in the background(by virtue of the application initiating a connection request), inaccordance with an embodiment. As an option, the method 200 may beimplemented in the context of any one or more of the embodiments setforth in any previous and/or subsequent figure(s) and/or the descriptionthereof. For example, the method 200 may be carried out by the wirelessdevices 104A, 104B of FIG. 1. However, it is to be appreciated that themethod 200 may be implemented in other suitable environments.

As shown, in operation 202, a connection request from an applicationrunning as a background process on a wireless device (e.g. wirelessdevices 104A, 104B of FIG. 1, etc.) is received. In the context of thepresent description, such connection request may refer to any command,instruction, inter-process communication (IPC), or any other signal thatresults in (or even includes) a connection request radio frequency (RF)signal being transmitted from the wireless device.

For example, in use in accordance with one embodiment, after thewireless device receives a connection request from an upper layerapplication, the device may select a random access preamble, andtransmit such random access preamble to the base station (e.g. basestation 106 of FIG. 1, etc.) to start a random access procedure whosepurpose is to create an active connection between the wireless deviceand a base station (e.g. the base station 106 of FIG. 1). It should benoted that the aforementioned random access preamble may include anyrandom access resource and may also be referred to as a random accessrequest. More information regarding such random access preamble/requestand the corresponding random access procedure will be set forth duringthe description of FIG. 2B. Still yet, in addition to the aforementionedconnection request (and any following random access procedure) directlyoriginating from an application installed on a wireless device, theaforementioned connection request (and any following random accessprocedure) may, in other embodiments, indirectly originate from theapplication as a result of actions by a user of the wireless device,and/or any other hardware and/or software of the wireless device inconnection with the application.

As an option, it may be determined whether the connection requestoriginated from the application running as the background process on thewireless device. Such determination may be carried out in any desiredmanner. For example, the method 200 may, in one possible embodiment,access a data structure that maintains a list of all applicationscurrently running in the background, in order to discern whether theconnection request originated from an application on such list. In otherpossible embodiments, a check may be performed to discern whether theconnection request originated as a result of real-time user input or inconnection with other indicia of foreground processes (e.g. graphicsprocessor usage, etc.) and, if so, conclude that the application is notrunning as a background process.

Assuming that a random access procedure is/remains unsuccessful, it isthen determined, in decision 206, whether one or more random accessprocedure criteria (hereinafter “criteria”) is met. In a first optionalembodiment, such one or more criteria may involve a failed random accesspreamble transmission threshold number, and the determination as towhether the one or more criteria is met (per decision 206) may includecomparing a number of failed random access preamble transmissions tosuch threshold number. In the context of the present description, therandom access procedure may include any process of exchanging one ormore signals for the purpose of establishing a communication connectionbetween the wireless device and a network. Further, a failed randomaccess procedure may, in one possible embodiment, refer to a situationwhere a random access request is transmitted by the wireless device, buta random access response is not received for a predetermined amount oftime.

In a second optional embodiment (that may be used as a substitute for orsupplement the first optional embodiment), the one or more criteria mayinvolve a threshold number of random access procedure messagecollisions, and the determination as to whether the one or more criteriais met (per decision 206) may include comparing a number of randomaccess procedure message collisions to the threshold number. In thepresent description, a random access procedure message collision mayrefer to a situation where any connection request-prompted signalingmessage is transmitted by the wireless device, but a response to suchconnection request-prompted signaling message is not received for apredetermined amount of time. In various embodiments, the aforementionedsignaling message may include a random access preamble or subsequentsignaling message such as a scheduled transmission [e.g. radio resourcecontrol (RRC) connection request], and the response may include a randomaccess response and/or a contention resolution message. More informationregarding such signaling messages and responses will be set forth duringthe description of FIG. 2B.

To this end, the second optional embodiment may take into account moremessages than the first optional embodiment, when determining whetherthe one or more criteria is met per decision 206. Further, it should benoted that the aforementioned thresholds may be statically predeterminedor dynamically determined in any desired manner by the wireless deviceand/or base station (or other network component) via direct or broadcastsignaling.

It should be noted that, in various embodiments, the aforementionedthresholds may be triggered for a variety of reasons. For example, apreamble (or other subsequent message) may be transmitted from aparticular wireless device at a same time/frequency resource as anotherwireless device, resulting in the base station receiving a garbledsignal that results from message interference. In another embodimentwhere preambles are randomly selected by wireless devices, a situationmay arise where two different wireless devices randomly select the samepreamble by coincidence. In such situation, the base station may respondto only one of such wireless devices (or neither).

In response to the determination that the one or more criteria is met,at least one aspect of a random access procedure resulting from theconnection request that originates from the application running in thebackground on the wireless device, is restricted. See operation 208. Inthe context of the present description, such aspect(s) may refer to oneor more messages of the random access procedure itself (e.g. theircontents, format, etc.), or a manner (e.g. time, frequency, etc.) inwhich such message(s) are transmitted or otherwise processed. Further,restriction of such aspect(s) may be accomplished, in variousembodiments, by controlling the random access procedure-related messagesthemselves and/or any signaling (e.g. connection requests, etc.) thatcauses or otherwise prompts initiation of the random access procedure.

With continuing reference to FIG. 2A, the random access procedure may beperformed in operation 210 to establish the communication connection forthe connection request. Further, to the extent that operation 208 isperformed prior, the random access procedure is performed with arestriction of the at least one aspect. In the context of the presentdescription, the aforementioned restriction may refer to any act oromission that results in less random access attempts being in the needof servicing at least for a given point in time (e.g. real-time, duringa time period, etc.). Still yet, the random access procedure aspect(s)may involve the abovementioned connection request (received in operation202), and/or subsequent random access procedures (or related messages),in so far as the random access procedure indirectly originates from thebackground application (by virtue of the background applicationgenerating the connection request that initiates the random accessprocedure). In various embodiments, the foregoing restriction maycorrespond to a limit of one or more capabilities or features of therandom access procedure (e.g. based on changes or updates inconfigurations or settings of such random access procedure).

For instance, in one possible embodiment where the aforementionedaspect(s) includes a transmission of random access attempt requests, theaspect(s) (that is/are restricted) may include a time between thetransmission of a plurality of random access attempt requests. Just byway of example, a time between random access attempt requests may beaugmented, so that fewer of such random access attempt requests occur ata given time (or time period). In another embodiment, the aspect(s) mayinclude a number of the random access attempt requests that aretransmitted. For example, the number of such random access attemptrequest transmissions may be reduced, so that fewer of such randomaccess attempt requests occur at a given time (or time period).

In another embodiment where the aforementioned aspect(s) includes one ormore subsequent connection requests, the aspect(s) of the random accessprocedure may be restricted by throttling the one or more subsequentconnection requests. For example, a number or frequency of thesubsequent connection requests may be reduced which, in turn, results infewer or delayed random access procedures since it is the connectionrequest(s) that prompts initiation of the corresponding random accessprocedure.

Further, it should be noted that the foregoing aspect(s) may berestricted using any desired mechanism. For instance, the aspect(s) maybe restricted utilizing an increased back off parameter value. In thecontext of the present description, such back off parameter value refersto a parameter assigned to wireless devices that dictate a priority withwhich the wireless device is serviced. For instance, a lower back offparameter value may result in higher priority servicing (e.g. theaspect(s) may not be restricted in the manner set forth earlier).Further, increasing the back off parameter value may result in a higherback off parameter value which, in turn, may result in lower priorityservicing (e.g. the aspect(s) may be restricted in the manner set forthearlier).

In normal operation (e.g. when decisions 204 or 206 are answered in thenegative) and an access attempt fails, the device waits a random backoff time prior to starting the random access procedure again. Such backoff time is randomly generated according to a uniform distributionbetween 0 and a back off parameter value. By this design, there is arandom distribution of priorities amongst devices. However, when therestriction of operation 208 occurs, the back off parameter may bepurposefully selected to be a higher number, resulting in any of theaforementioned restrictions of any of the aforementioned aspects.

In still another embodiment, the aforementioned aspect(s) may berestricted utilizing a timer. For example, in one possible embodiment,such timer may dictate a duration of time before which a wireless devicemay attempt a reconnection by initiating a random access attempt (andassociated request). This may be accomplished, for example, byrestricting when the background application may be allowed to cause aconnection request. Specifically, when the restriction of operation 208occurs, the timer may be augmented (in connection with one or morebackground process-related applications) so as to restrict thebackground application from originating a connection request before thetimer expires which, in turn, prevents random access attempt requestsfrom occurring before the timer expires. Further, similar to the settingof the aforementioned threshold, etc.; the aspect(s) of the one or morerandom access attempt procedure may be restricted by the wireless device(by the one or more criteria being configured by the wirelesscommunication device), by a network to which the wireless device isconnected (by the one or more criteria being received at the wirelesscommunication device from a base station of the network), or both.

More illustrative information will now be set forth regarding variousoptional architectures and uses in which the foregoing method may or maynot be implemented, per the desires of the user. It should be noted thatthe following information is set forth for illustrative purposes andshould not be construed as limiting in any manner. Any of the followingfeatures may be optionally incorporated with or without the otherfeatures described.

FIG. 2B illustrates a sample random access procedure 210, in accordancewith one embodiment. As an option, the random access procedure 210 maybe implemented in the context of any one or more of the embodiments setforth in any previous and/or subsequent figure(s) and/or the descriptionthereof. For example, the random access procedure 210 may be carried outin the context of the network 108 of FIG. 1 and may be carried out inaccordance with an LTE or LTE-A standard communication protocol.However, it is to be appreciated that the random access procedure 210may be implemented in other suitable environments.

The sample random access procedure 210 reflects a contention-basedrandom access procedure between a base station 211-1 (e.g. the basestation 106 of FIG. 1) and a wireless device 211-2 (e.g. the wirelessdevices 104A, 104B of FIG. 1), where the wireless device 211-2transitions from an idle state to a RRC connected state, etc., asopposed to a contention free random access which might occur at ahandover. When the wireless device 211-2 transitions from the idle stateto the RRC connected state, a network is unable to dictate whichpreamble (out of 64 (or less) possible values) should be used. Thus, thewireless device 211-2 uses one of the possible preambles that israndomly selected. As mentioned earlier, such protocol opens up thepossibility of a collision if the same preamble is being used by twodevices.

As shown in FIG. 2B, the random access procedure 210 is carried outbetween the base station 211-1 and the wireless device 211-2, where thewireless device 211-2 includes a lower layer application and/or modemprocessor 211-2A [e.g.transport/network/data-link/physical-International StandardsOrganization (ISO) layer application/processor], and an upper layerapplication and/or application processor 211-2B (e.g.application/presentation/session-ISO layer application/processor).Further, the random access procedure 210 is prompted by a connectionrequest by being sent by the upper layer application 211-2B to the lowerlayer application/modem processor 211-2A, as indicated in operation A.

Once initiated by operation A, the random access procedure 210 startswith the wireless device 211-2 sending a random access preamble 212 inconnection with a LTE Random Access Request. See operation 1. The basestation 211-1 then sends (and the wireless device 211-2 receives) a LTERandom Access Response 214 in response to the random access preamble212, assuming there is no collision or preamble failure. See operation2. In response to the LTE Random Access Response 214, a scheduledtransmission 216 is sent in the form of a LTE Layer 2/Layer 3 Message(e.g. RRC connection request message). See operation 3. The base station211-1 then sends (and the wireless device 211-2 receives) a LTEContention Resolution Message 218. See operation 4.

As mentioned earlier in the context of the method 200 of FIG. 2A, theseand/or any additional random access procedures and connection requestsmay be restricted as result of the failure to receive a threshold numberof any of the response messages (e.g. LTE Random Access Response 214,LTE Contention Resolution Message 218, etc.). More information will nowbe set forth regarding a specific method by which such restriction maybe triggered and carried out.

FIG. 3 illustrates a method 300 for restricting a random accessprocedure in connection with a connection request that originates froman application running a background process on a wireless device, inaccordance with an embodiment. As an option, the method 300 may beimplemented in the context of any one or more of the embodiments setforth in any previous and/or subsequent figure(s) and/or the descriptionthereof. For example, the method 300 may be carried out by the wirelessdevices 104A, 104B of FIG. 1 and/or incorporate one or more features ofthe method 200 of FIG. 2. However, it is to be appreciated that themethod 300 may be implemented in other suitable environments.

As shown, a connection request is received in operation 302 after whichit is determined whether the connection request is a result of abackground data connection per decision 304. If not, the method 300continues by operation in accordance with standard (e.g. normal) randomaccess procedure (RACH), per operation 306.

On the other hand, if it is determined that the connection request is aresult of a background data connection per decision 304, a specialbackground data connection RACH is triggered that begins with theinitialization of a threshold number of failed preamble transmissions(e.g. Nmax_num_preamble_trans_of_background_data). See operation 308. Asmentioned earlier, such threshold may be dynamically configured by thewireless device and/or base station (or other network componentry), inany desired manner. In terms of configurability, a larger value for suchthreshold may reduce a frequency of any restrictions on random accessprocedure (e.g. restriction on transmission of random access preambles),since such threshold is triggered less often. Conversely, a smallervalue for such threshold may increase a frequency of any restrictions onthe random access procedure (e.g. restriction on transmission of randomaccess preambles) in connection with the background process-relatedconnection request. For connection requests originating from anapplication running in the background, the maximum number of failedpreamble transmissions may thus be configured to be smaller than anormal/common threshold value used/received from a base station. Asmaller value for such threshold may also reduce a maximum transmitpower of the random access preamble of the wireless communication devicewhich, in turn, may reduce radio interference on the network.

With continuing reference to FIG. 3, a random access resource isselected per operation 310. In one embodiment, a random access resourceselection procedure may be performed in accordance with that defined bythe 3GPP standard, for use in transmitting a random access preamble(which is a first/initial message in the RACH), as indicated inoperation 312. As mentioned previously, such preamble may be randomlyselected from a predetermined range of preamble values.

It is then determined whether the RACH was successful per decision 314.Specifically, it is determined whether required connection-relatedresponses (e.g. response 214, 218 of FIG. 2) have been received within apredetermined timeframe (as dictated by timer values broadcasted by abase station). If so, it may be assumed that the RACH procedure isproceeding properly and there is no reason to continue with the specialbackground data connection RACH. See operation 316.

However, if it is determined that the RACH was not successful perdecision 314, it is additionally determined whether a transmission ofRRC connection request timer has expired per decision 318. In use, suchtimer stops upon achieving a successful RACH (i.e. upon receiving aresponse to the RRC connection request). Before such timer has expired,the method 300 proceeds to operation 322 in an attempt to achieve asuccessful RACH. If a successful RACH is not achieved by the expirationof the timer per decision 318, the method 300 indicates a RACH failureto upper layers in operation 320.

With that said, if a successful RACH is not achieved but the timer hasnot expired per decision 318, the method 300 continues by incrementing apreamble transmission counter by one in operation 322, since there isone preamble transmission per each random access procedure. Next, it isdetermined in decision 324 whether a current value of the preambletransmission counter is greater than the corresponding thresholdinitialized in operation 308 (e.g.Nmax_num_preamble_trans_of_background_data). If not, another RACH may beinitiated in operation 310.

However, if it is determined in decision 324 that the preambletransmission counter is indeed equal to the corresponding threshold, arestriction of the background process-related connection requests isinitiated in operation 326. Specifically, in the present embodiment, aback off parameter value may be set to be a predetermined value (e.g.background_data_back_off_parameter). As mentioned earlier, a value ofsuch back off parameter may be raised, in order to lower a priority withwhich the background process-related connection requests are managed.

In various embodiments, such increased back off parameter value (that islarger than a current normal one which is used for connection requestsoriginating from any and all applications) may be statically (e.g.predetermined) or dynamically configured by the wireless device and/orbase station (or other network componentry), in any desired manner. Interms of configurability, a larger value for such back off parameterreduces the frequency of random access request/preamble transmission forbackground process-related connection requests, since a larger back offparameter triggers random access preamble transmission less often. Thismay, in turn, reduce collisions during a random access procedure inconnection with foreground process-related connection requests.

The foregoing back off parameter may be implemented in various ways inaccordance with different embodiments. For example, in one possibleembodiment, a back off parameter may be used which is defined inaccordance with a predetermined communication protocol (e.g. LTE, LTE-A,and/or an advanced permutation thereof, etc.). As mentioned earlier,such back off parameter may, in the absence of any congestion (per theprevious operations), be randomly generated for the correspondingwireless device, so that there is a random distribution of prioritiesamongst devices. However, in operation 326, such back off parameter maybe proactively increased in order to de-prioritize backgroundprocess-related connection requests. In various aspects of the presentembodiment, such increase may involve setting the back off parameterabove a predetermined threshold value, or randomly select a back offparameter from a range of values that are all above a threshold value.

In still other embodiments, the aforementioned increase in back offparameter value may be implemented using different back off parametersthat may be used for different situations. For example, a particularback off parameter may be used for normal operation (and in connectionwith all foreground/background applications), while a separate, specialback off parameter (with a higher value) may be used for implementingoperation 326. In any of the previous embodiments, and strictly as anoption, the adjusted value of such back off parameter (as well as theaforementioned threshold value) may be reverted to a previous valueafter operation 326, and/or in the event of network congestion returnsto normal levels (i.e. decisions 314, 318 are not/no longer triggered,etc.).

FIG. 4 illustrates a method 400 for restricting the transmission of arandom access preamble in connection with a connection request thatoriginates from an application running in background process on awireless device, in accordance with another embodiment. In oneembodiment, this may be accomplished by restricting one or moreconnection requests that originate from an application running on awireless device when the device detects cell congestion. As an option,the method 400 may be implemented in the context of any one or more ofthe embodiments set forth in any previous and/or subsequent figure(s)and/or the description thereof. For example, the method 400 may becarried out by the wireless devices 104A, 104B of FIG. 1 and/orincorporate one or more features of the method 200 of FIG. 2. However,it is to be appreciated that the method 400 may be implemented in othersuitable environments.

Similar to the embodiment described in connection with the previousfigure, a connection request is received in operation 402 after which itis determined whether the connection request is a result of a backgrounddata connection per decision 404. If not, the method 400 continues byoperation in accordance with a standard (e.g. normal) RACH, peroperation 406. On the other hand, if it is determined that theconnection request is a result of a background data connection perdecision 404, a special background data connection RACH is triggeredthat begins with the initialization of a threshold number of collisions(e.g. Nmax_num_collision). See operation 408.

As mentioned earlier, such threshold may be statically (e.g.predetermined) or dynamically configured by the wireless device and/orbase station (or other network componentry), in any desired manner. Interms of configurability, a larger value for such threshold may reduce afrequency of any restrictions on background process-related connectionrequests which, in turn, may reduce a frequency of any restrictions ontransmissions of random access preambles since such threshold istriggered less often. Conversely, a smaller value for such threshold mayincrease a frequency of any restrictions on background process-relatedconnection requests. This, in turn, may increase a frequency of anyrestrictions on transmissions of a random access preamble.

With continuing reference to FIG. 4, a random access resource isselected per operation 410. As mentioned earlier, the random accessresource selection procedure may be performed in accordance with thatdefined in the 3GPP standard, for use in transmitting a random accesspreamble (which is a first/initial message in the RACH), as indicated inoperation 412.

It is then determined whether the RACH was successful per decision 414.Specifically, it is determined whether required connection-relatedresponses (e.g. response 214, 218 of FIG. 2) have been received within apredetermined timeframe (as dictated by timer values broadcasted by abase station). If so, it may be assumed that the RACH procedure isproceeding properly and there is no reason to continue with the specialbackground data connection RACH. See operation 416.

However, if it is determined that the RACH was not successful perdecision 414, it is additionally determined whether a transmission ofRRC connection request timer has expired per decision 418. In use, suchtimer stops upon achieving a successful RACH (i.e. upon receiving aresponse to the RRC connection request). If a successful RACH is notachieved by the expiration of the timer per decision 318, the method 400indicates a RACH failure to upper layers in operation 320.

With that said, if a successful RACH is not achieved but the timer hasnot expired per decision 418, the method 400 continues by incrementing apreamble transmission counter by one in operation 422, since there isone preamble transmission per each random access procedure. Next, it isdetermined in decision 424 whether a collision has been detected.Specifically, it is determined whether one or more connection-relatedresponses (e.g. response 214, 218 of FIG. 2) has not been receivedwithin a predetermined timeframe. If so, the method 400 continues byincrementing a collision counter by one in operation 426. To this end,it may be determined in decision 428, whether a current value of thecollision counter is greater than the corresponding thresholdinitialized in operation 408 (e.g. Nmax_num_collision). If not, anotherRACH may be initiated in operation 410.

However, if it is determined in decision 428 that the collision counteris indeed equal to the corresponding threshold, a restriction of thebackground process-related connection requests is initiated in operation430. As mentioned earlier, such timer may dictate a duration of timebefore which a wireless device may attempt to access the correspondingbase station again by initiating a connection request (see, again,operation 402). Specifically, the timer may be augmented so as torestrict background process-related connection requests so that they maynot occur for the period of time (i.e. before the new timer expires). Itshould be noted that, in various embodiments when the wireless devicedetects that it is has traveled out of a congested cell area, the devicemay cancel the timer, and reset the collision number count.

By this design, the method 400 of FIG. 4 differs from the method 300 ofFIG. 3, by virtue of the trigger that is used to initiate the specialbackground data connection RACH (e.g. collision vs. preamble failure,etc.), as well as the specific technique used to restrict backgroundprocess-related connection requests (e.g. timer vs. back off parameter,etc.).

FIG. 5 illustrates a method 500 for restricting a random accessprocedure in connection with a connection request that originates froman application running a background process on a wireless device, inaccordance with another embodiment. As an option, the method 500 may beimplemented in the context of any one or more of the embodiments setforth in any previous and/or subsequent figure(s) and/or the descriptionthereof. For example, the method 500 may be carried out by the wirelessdevices 104A, 104B of FIG. 1 and/or incorporate one or more features ofthe method 200 of FIG. 2. However, it is to be appreciated that themethod 500 may be implemented in other suitable environments.

Similar to the embodiments described in connection with the previous twofigures, a connection request is received in operation 502 after whichit is determined whether the connection request is a result of abackground data connection per decision 504. If not, the method 500continues by operation in accordance with standard (e.g. normal) RACH,per operation 506. On the other hand, if it is determined that theconnection request is a result of a background data connection perdecision 504, a special background data connection RACH is triggeredthat begins with the initialization of a threshold number of collisions(e.g. Nmax_num_collision). See operation 508.

As mentioned earlier, such threshold may be statically (e.g.predetermined) or dynamically configured by the wireless device and/orbase station (or other network componentry), in any desired manner. Interms of configurability, a larger value for such threshold may reduce afrequency of any restrictions on background process-related connectionrequests, which, in turn, may reduce a frequency of any restrictions ontransmissions of random access preambles since the threshold istriggered less often. Conversely, a smaller value for such threshold mayincrease a frequency of any restrictions on background process-relatedconnection requests. This, in turn, may increase a frequency of anyrestrictions on transmissions of a random access preamble.

With continuing reference to FIG. 5, a random access resource isselected per operation 510. As mentioned earlier, a random accessresource selection procedure may be performed in accordance with thatdefined by the 3GPP standard, for use in transmitting a random accesspreamble (which is a first/initial message in the RACH), as indicated inoperation 512.

It is then determined whether the RACH was successful per decision 514.Specifically, it is determined whether connection-related responses(e.g. response 214, 218 of FIG. 2) have been received within apredetermined timeframe (as dictated by timer values broadcasted by abase station). If so, it may be assumed that the RACH procedure isproceeding properly and there is no reason to continue with the specialbackground data connection RACH. See operation 516.

However, if it is determined that the RACH was not successful perdecision 514, it is additionally determined whether a transmission ofRRC connection request timer has expired per decision 518. In use, suchtimer stops upon achieving a successful RACH (i.e. upon receiving aresponse to the RRC connection request). Before such timer has expired,the method 500 proceeds to operation 522 in an attempt to achieve asuccessful RACH. If a successful RACH is not achieved by the expirationof the timer per decision 518, the method 500 indicates a RACH failureto upper layers in operation 520.

With that said, if a successful RACH is not achieved but the timer hasnot expired per decision 518, the method 500 continues by incrementing apreamble transmission counter by one in operation 522, since there isone preamble transmission per each random access procedure. Next, it isdetermined in decision 524 whether a collision has been detected.Specifically, it is determined whether one or more connection-relatedresponses (e.g. response 214, 218 of FIG. 2) has not been receivedwithin a predetermined timeframe. If so, the method 500 continues byincrementing a collision counter by one in operation 526. To this end,it may be determined in decision 528, whether a current value of thecollision counter is greater than the corresponding thresholdinitialized in operation 508 (e.g. Nmax_num_collision). If not, anotherRACH may be initiated in operation 510.

However, if it is determined in decision 528 that the collision counteris indeed equal to the corresponding threshold, a restriction of thebackground process-related connection requests is initiated in operation530. Specifically, in the present embodiment, a back off parameter valuemay be set to be a predetermined value (e.g.background_data_back_off_parameter). As mentioned earlier, a value ofsuch back off parameter may be raised, in order to lower a priority withwhich the background process-related connection requests are managed.

In various embodiments, such increased back off parameter value (that islarger than a current normal one which is used for connection requestsoriginating from any and all applications) may be statically (e.g.predetermined) or dynamically configured by the wireless device and/orbase station (or other network componentry), in any desired manner. Interms of configurability, a larger value for such back off parameterreduces the frequency of random access request/preamble transmission forbackground process-related connection requests, since a larger back offparameter triggers random access preamble transmission less often. Thismay, in turn, reduce collisions during a random access procedure inconnection with foreground process-related connection requests.

By this design, the method 500 of FIG. 5 differs from the method 300 ofFIG. 3, by virtue of the trigger that is used to initiate the specialbackground data connection RACH (e.g. collision vs. preamble failure,etc.), but uses a similar technique to restrict backgroundprocess-related connection. Thus, various embodiments are described thatmay possibly improve a user-requested connection access attempt successrate and connection establishment speed, by restricting a wirelessdevice making background data connection requests, thereby slowing downrandom access transmission attempts during certain conditions. This, inturn, may be particularly beneficial in cases of excessive demand. Tothis end, a better mobile communication device user experience may beprovided in some embodiments.
